を型内に江人する方法等が既に提供されている。For example, an in-line screw set injection molding machine can be used to melt and plasticize the resin and inject it into the mold. Alternatively, the required amount of resin can be put into a cylindrical cartridge, the cartridge can be heated with a separate heating device, and the resin can be heated inside the cartridge. A method has already been proposed in which the resin is melted and the melted resin is poured into the mold using a hydraulic piston or the like located at the top.

ラツキがあり、１個以上の＠歯床を得る場合に成形機内
の洗掃が煩雑で多大の時間を要する欠点を有している。However, in the former method, molten IN fg is produced in the heating cylinder after each molding, resulting in variations in quality for each molding, and cleaning inside the molding machine is complicated when obtaining one or more tooth beds. It has the disadvantage that it takes a lot of time.

栂脂の成形品の製造にも適用できる。According to the resin molding machine of the present invention, especially when a resin heating cylinder having a through hole as described above is used, a removable resin receiving cover is provided at the bottom, and a mold receiving stand that is movable up and down is installed. As a result, a predetermined amount of resin is heated and melted in a short time, and the resin heating cylinder can be easily cleaned after each molding, so the molding cycle is quick and stable, and a product of excellent quality can be obtained. It is extremely easy to manufacture a wide variety of molded products by replacing not only the same type of mold but also desired molds. Therefore, the resin molding machine of the present invention is suitable for the W construction of denture bases made of polycarbonate resin, polysulfone resin, etc., but is not limited thereto, and can also be applied to the manufacture of molded products made of thermoplastic toga resin in general.

This prevents the resin from falling from the resin discharge port in this state. That is, reception (6
) is generally horizontally rotatable around a fulcrum (15), and a spring (14) allows - (13) on the pedestal (6) to come into close contact with the discharge port of the heating cylinder (3). (
Figure 1). At the same time, when the resin in the heating cylinder (3) is melted, the receiving cover (6) is pushed down with the lever (16), and the heating cylinder is moved laterally around the fulcrum (15). The discharge port (3) is in an open state, and the molten resin is pumped into the mold (
7) is easily injected (Fig. 2).

に密着せしめる。When injecting the molten resin into the mold (7), the resin heating cylinder discharge port and the injection port of the mold must be tightly contacted to prevent resin from leaking during injection. Therefore, in the present invention, a mold holder (8) that can be moved up and down by a hydraulic jack or the like is installed at the bottom of the heating cylinder (3), and the outlet of the heating cylinder (3) and the mold (7) are connected to each other. Makes a strong contact with the injection port.
